PIPE-COUPLING.

Specification of Letters Patent.

Application filed. April 15, 1913. Seria1ifl'o.f761,21 9'.

- To all whom it may m;

Be it known that I, EUGENE JfKnL'LY, a citizen of the United States,residing at Vashington city, in the District ofColumhia, have inventedcertain new and useful Improvements in Pipe-Couplers, of which thefollowing is aspecification.

My invention relates to pipe-couplers, for use in coupling all kinds ofpipes either exposed or underground; and more particularly to connectpipes where a close union,- strength and lasting qualities are desired,such as gas, water pipes, and the like.

The object of the invention is to construct a coupler that may be easilyand cheaply manufactured, will be durable, the parts thereof may beseparately made, may be easily replaced when worn; may be assembled withlittle effort; and will be absolutely impervious and prevent anyleakage.

In the drawings forming a part of this specification, and in which likesymbols of reference represent corresponding parts in the several views:-Figure l is a section of pipe with my invention applied thereto; Fig.2 is a longitudinal section to show the connection of the parts; Fig. 8is a transverse view, on the line 33, Fig. 1, looking in the directionof the arrows; Fig. 4: is a plan View of the one of the clamps; Fig. 5is an inverted view of the connecting arm or clamp; Fig. 6 is a view ofthe arc-shaped recess formed in the head of the outer section; Fig. 7 isa modified form of clamp, showing the same adjustable; Fig. 8 is a planview of the modification; and Fig. 9 is a view of the modification,transverse to Fig. 7, on line 99, looking in the direction of arrow.

The numeral 1 denotes one section of pipe and 2 the other.

3 is a collar, having a shoulder 4, in which a series of arc-shapedrecesses 18 are cast or formed; and 5 is a recess formed at the base ofthe arcshaped recess.

6 are curved lugs formed on the section 1, the same having recesses attheir bases,

said recesses being on the outer face of the same. i

7 are tongues or arms formed on clamps 8, the object of the same beingto take into the recesses on the lugs 6.

19 are lugs on clamps 8, the same having lips 20 to be received in therecesses 5.

9 is an adjustable section on the arm 8, the purpose of the same beingto adjust said arm when necessary .toconform to pipe but as the samewould seldom be required I the same.

14; is a corrugated surface or ratchet,

shown as a modification, on the part 9 so as to engage and hold the sameagainst the lugs; but the same not belng necessary is ndt generallyused.

13 shows the end of the tongue 7 struck down after the parts are inoperative position.

.15 is a slot formed in arm 8fto permit adjustment of parts; '16 is aring or gasket at the ends of the pipe sections; and 17 is acircumferential groove in the outer pipe section so that the gasketbeing forced against the same makes a more perfect union.

The operation of the coupling will be apparentfrom the foregoing. Thearms or clamps are cast or formed separately; the pipe sections areformed with the lugs and recesses in the same; and a gasket is placedbetween the sections. placed in position and driven home with a hammeror other instrument, and the lip 7 struck down firmly locking the same.For a four-inch pipe three braces are usually preferred; but for alarger pipe of course more are better.

Having now fully described my invention, what I claim as new and desireto secure by Letters-Patent, is

1.'The combination with sections of a pipe, one section formed withpivotal recesses and the other section with inclined lugs, of clamps toengage the recesses and be swung over the lugs to draw the sectionstogether and secure them in positi0n.-

2. The combination with sections of a pipe, one section formed withpivotal recesses and the other section with inclined lugs, of clamps toengagethe recesses and be swung over the lugs to draw the sec.- tionstogether, and a tongue on the clamps to engage the inclined lugs and bestruck down and lock the sections together.

3. A pipe coupling, comprising a section formed with pivotal recesses, asecond section formed with inclined and undercut lugs, and clampsadapted to engage the recesses and be swung over the lugs, so as toPatented Sept; 9, 1913.

The arms are then draw said sections together and hold the same.

4. The combination with the sections of a pipe, one section formed withpivotal recesses undercut at their bases and the other section withinclined lugs undercut at their bases, of clamps having lugs formed withflanges to engage the undercut portion of the recesses and be swung overthe lugs and engage the undercut recess of the same so that the sectionsof pipe may be drawn together and secured in position.

5. The combination with the sections of a pipe, one section formed withpivotal rethe lugs and engage the undercut recesses of the same, and agasket between the pipe sections, so that the sections may be drawntogether and secured in position.

6. The combination with the sections of a pipe, one section formed withinclined lugs and the other section with pivotal recesses, of clampsformed'with lugs adapted to engage the lugs and recesses of thepipe-sections, and a tongue formed on the lu -engaging section andadapted to be struck down to lock the parts when brought together;

In testimony whereof I affix my slgnature in presence of two witnesses.
